The new Audi RS7 is one of the last four high-performance doors from Ingolstadt to be appreciated by car buyers in the United States. Under his undeniably elegant and aggressive body, he has punch.
The 4.0-liter twin-turbo V8 that powers this monster comes with a peak power of 591 horsepower (441 kilowatts) and 590 pound-feet of torque (800 Newton meters), sent to all four wheels via Audi’s Quattro .
Note that the RS7 Sportback is the most powerful Audi A7 to date.
But the RS7 is not without a worthy opponent. Enter the Mercedes-AMG GT63 S. The four-door coupe is also powered by a 4.0-liter twin-turbo V8 engine, coded AMG M177, developing 630 hp (470 kW) and 664 lb-ft (900 Nm) of torsion – also sent to all four wheels but with a bias at the rear.
With these figures presented, it is obvious that the Audi RS7 Sportback perfectly matches the AMG GT63 S – although that of Stuttgart has a little advantage. It is important to note, however, that the Mercedes is a little heavier than the Audi, the latter having a weight advantage of 55 kilograms (121 pounds).
The Mercedes is also more expensive than the Audi. To be honest, it’s a lot more expensive, but you should all know by now.
